Great stuff Gringo,
I have just built 20 GW Skitarii , lovely minis with lots of detail.
Being an addict scratchbuilder I am going to build me a robot like torso + legs so as to use the remaining heads & arms.
So this could also be a good idea / opportunity for you , make armless / headless minis using the ones you have already done for scratchbuilders. They would be cheaper, lighter & appeal to quite a number of gamers.
You can always make a poll to gauge the responce.
Oh & that robo dog would make a great addition to an Adeptus Arbites Killteam / Necromunda Patrol , which I am sure will eventually come out. Judge Dredd will not be left out !!!
Keep it up
Z
